Root's run-scoring streak faces tough test against India, Australia: Ian Chappell

Joe Root surpasses Alastair Cook as England's top Test run-scorer, facing upcoming challenges against India and Australia.

Joe Root's impressive form since resigning as England captain will be put to test in the upcoming series against India and Australia when his skills against pacers and spinners will be "scrutinised", reckons Australian great Ian Chappell.

With 10 centuries in just 54 innings over the past two and a half years, Root has gone past Sir Alastair Cook as England's highest Test run-scorer.

"Root's phenomenal run-making will again be tested when first he faces India at home and then Australia away. In those two series, Root will be facing the best attacks in Test cricket, and his technique against both pace and spin will again be fully scrutinised," the 81-year-old wrote in his column for ESPNCricinfo.

India are scheduled to tour England for a four-match Test series next summer and the Three Lions will face the challenge to regain the Ashes later next year in Australia.

"Those are difficult challenges that Root and England will face in the future. Currently, they're desperately involved in a bid to win after Pakistan levelled their three-game series with a spin-revolution victory against a clueless England."

The Ben Stokes-led side is currently under the pump after Pakistan levelled the three-match series 1-1. The third Test begins on October 24.

"As the most technically gifted, Root will have the task of convincing his fellow team-mates that numerous versions of the sweep shot aren't the ideal way to combat good spinners. Despite Root's proven talent, that will be a very difficult task," he added.
